A representative menu is posted. Item names and setting value are subject to change.
*1 At Cool and Heat Hi speed trim, *VZC200601* with **VC960804C,
**VM970804C and *MVC800804C combination trim more than 5% settings are invalid. Trimmed up CFM makes miss matching error.
*2 Other than the above, depending on the connected indoor unit, there are restrictions on the positive side Trim setting.
If you want to change the Cool Airow Trim to positive side, be sure to conrm the Airow Trim restrictions in the latest indoor unit installation manual.
The latest manual can be obtained from the website “PartnerLink(InfoFinderPlus/Literature)”.

*3 The Inverter system uses lower compressor speed and lower indoor unit CFM to optimize system performance.
To obtain 100% CFM for home circulation, use full Trim setting instead of Int/Low speed.
This is recommended for applications with unusually cold return temperatures such as basements.
*4 Please refer to the page of “DEHUMIDIFICATION SELECT “ for details of this function.
SUBMENU ITEM INDICATION(Units) COMMENTS
BOOST MODE ENABLE OFF or ON
BOOST MODE is ON by default. See BOOST
MODE section of this manual for more details.
BOOST TEMP Always Active or 70F to 105F in icrements
If enabled, when the ambient outdoor temperature
is greater than this selected value, boost mode will
be operational.
Below this temperature the mode will not function.
There is also an option to keep boost mode
countinuously enabled.
INDOOR/OUTDOOR HEIGHT DIFFERENCE
Both Units at Same Level,
Outdoor Unit is Lower, or
Indoor Unit is Lower
If the outdoor & indoor units are within +/- 15 ft.
vertical distance, select SAME LEVEL. If the
outdoor unit is more than 15 ft. below the indoor
unit, select OUTDOOR LOWER. If the outdoor unit
is more than 15 ft. above the indoor unit, select
INDOOR LOWER.
RESET FOR SYSTEM SET UP NO or YES
Selecting yes will reset any system setting to their
factory defaults.
SYSTEM VERIFICATION TEST OFF or ON
System Verification Test must be run after
installation. This is approximately a 5-15 minute
test. If operation mode is set to COOL mode, the
system will enter CHARGE mode upon completion,
otherwise it will stop.
PUMP DOWN OFF or ON
Enter PUMP DOWN Mode.
This procedure runs the equipment for
approximately 15 minutes and allows accumulation
of refrigerant at
the outdoor unit for purposes of removing &
replacing the indoor unit or outdoor unit.
ACTIVATE CHARGE MODE OFF or ON
Enter Charging Mode. This allows for a steady
system operation for a duration of approximately 1
hour to allow for refrigerant charging of the system
via the charge port.
COOLING TRIM FACTOR(HIGH)
*1, 2
-15% to +15% in 5% increments
Select this airflow trim when inverter system is
running high compressor speeds during a cooling
cycle.
COOLING TRIM FACTOR(MID)
-15% to +15% in 5% increments,20 30, Full(Max)
*3
Select this airflow trim when inverter system is
running mid-range (intermediate) compressor
speeds during a cooling cycle.
COOLING TRIM FACTOR(LOW)
-15% to +15% in 5% increments,20 30, Full(Max)
*3
Select this airflow trim when inverter system is
running low compressor speeds during a cooling
cycle.
COOLING AIRFLOW PROFILE A, B, C, or D
If it is desirable to quickly ramp up the indoor airflow
select profile A.
If it is desirable to reach nominal airflow quickly, but
a slower ramp up time is required, select profile B.
If dehumidification is required immediately when
cooling mode begins select profile C.
If a slower airflow ramp up / ramp down time is
required in addition to dehumidification select profile
D.
BLOWER ON DELAY-COOLING 5, 10, 20 or 30 Seconds
Delay between compressor turning on and indoor
blower turning on during a cooling cycle.
BLOWER OFF DELAY-COOLING 30, 60, 90 or 120 Seconds
Delay between compressor shutting off and the
indoor blower shutting off after a cooling cycle.
